Two-hundred thirty nine people were arrested in San Bernardino County during the Labor Day enforcement period.

The “Avoid the 25 DUI Campaign” to remove suspected drunken drivers from the roadways — from August 15 to September 1 — netted 239 people for allegedly driving under the influence of alcohol or drugs, according to an Ontario Police Department news release.

Local police agencies, California Highway Patrol and San Bernardino County Sheriff’s conducted several operations — from DUI checkpoints to saturation patrols — throughout the region.

One of the operations met with some controversy from a protestor.

On Friday in San Bernardino, traffic officers held a DUI checkpoint in the 400 block of Tippecanoe Avenue.

Two blocks before motorists arrived to the checkpoint a protestor stood holding signs warning motorists of the checkpoint.

“I just don’t think it’s right for police to stop people who are driving home,” 35-year-old San Bernardino resident Alva Alvarez said. “Why should they check to see if someone has a license or not?”

Alvarez went on to say she doesn’t agree with people driving under the influence, but she also doesn’t agree with the checkpoints.

The Ontario Police Department is planning a checkpoint Friday night.

Between the hours of 6 p.m. and 2 a.m. police in that city will hold a checkpoint at an undisclosed location.

In Ontario, “over the course of the past three years, DUI collisions have claimed 12 lives and resulted in 38 injury crashes harming 53 of our friends and neighbors,” Ontario police Sgt. Bret Larson said. “Officers will be looking for signs of alcohol and or drug impairment as well as checking drivers for proper licensing delaying motorists only momentarily.”

Campaign funding is provided by grants from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
